Triumph Motorcycles America Issues Safety Recall for Certain Models

Triumph Motorcycles America has filed a safety recall report with the US National Highway Traffic Safety Administration (NHTSA) for specific models due to a potential engine stalling issue. The affected models include all 2022 through 2024 Triumph Trident 660s and 2022 through 2024 Triumph Tiger Sport 660 motorcycles. The engine stalling problem is caused by a hose obstruction and inaccurate sensor information being sent to the engine control unit (ECU), which can lead to an increased risk of a crash.

According to Triumph Motorcycles America's records, approximately 7,541 bikes could potentially be involved in this recall, representing 100 percent of the affected population. If you own a 2022 through 2024 Trident 660 or Tiger Sport 660, it is important to seek service for your bike as soon as possible.

The issue with the affected bikes is related to the manifold absolute pressure (MAP) hose becoming obstructed, which causes the MAP sensor to record incorrect information. This incorrect information is then sent to the ECU, which adjusts the fuel/air mixture based on the sensor's input. Without accurate information, the engine may experience an unstable idle and ultimately stall.

The affected 2021 through 2024 Triumph Trident 660s were produced between January 6, 2021, and July 27, 2023. The affected VIN range for these bikes is SMTL10UL5NTAE9988 to SMTL10UL8RTBP8186. On the other hand, the affected 2021 through 2024 Triumph Tiger Sport 660s were produced between August 3, 2021, and August 4, 2023. The affected VIN range for these bikes is SMTL20UL6NTAV5235 through SMTL20UL2RTBP8617.

If you notice an uneven engine idle, it may be a potential warning sign of this issue. Triumph authorized dealers will inspect and service the affected bikes at no cost to the customer. The service will involve replacing the original single hose with a new three-branch hose that has a different part number.

Triumph notified its dealer network in America on August 18, 2023, and issued a Stop Sale Notice for all affected bikes until the issue is resolved. Registered owners of the affected bikes will be notified by Triumph on or about August 31, 2023. Production bikes in both the Trident 660 and Tiger Sport 660 lines have already been equipped with the replacement part since August 8, 2023, and will not be subject to this recall.
